Re: Just whose confirmation bias?
If I may assist Santhanam Sundar  in my experience the people who are most likely to be critical of the vaccine project do not approach it from an ideological perspective or from lack of education, but rather because they have suffered some injury to themselves or their family. If they are then marginalised as “anti-vaxxers” or more politely “the vaccine hesitant” I am not sure whether this is a triumph of science or rough politics ?
There are perhaps no clear-cut messages from the past either .
